1 Claim.

The present invention relates to a radio time table which is intended toshow the programs on available broadcasting stations for predeterminedintervals during the day with the time table always visible for thecorresponding portion of the day.

According to the present invention radio programs are printed on a stripof paper with predetermined lengths of the strip allotted to successiveintervals of time for each day during the week. The strip is long enoughto incorporate, for example, hourly or quarter-hourly programs fromeight in the morning until midnight of each of the seven days of theweek, and this strip is advanced past an opening through which ie stripis visible so that at any predetermined hour the program for that hourmay be ascertained. The strip is advanced only during the portion of theday for which the program is printed, thereby reducing the requiredlength of strip for a full weeks program.

The objects and other features of the invention will hereinafter morefully appear, reference being had to the accompanying drawings in Which-Fig. 1 is a plan View of a device embodying the invention.

Fig. 2 is a plan View of the device on an enlarged scale and with thecover removed.

Fig. 3 is a vertical section along the line 3-3 of Fig. 2.

Fig. 4 is an end elevation of the device.

Fig. 5 is a fragmentary sectional view along the line 5--5 of Fig. 4,looking in the direction of the arrows.

Fig. 6 is an elevation of the front of a radio cabinet showing thedevice installed as an integral part thereof.

Fig. '7 is a plan View of a part of the time table or program.

Like reference characters refer to like parts in the different figures.

Referring first to Figs. 1 and 2, the device comprises a base I on whichis mounted a bracket 2 for supporting a roller 3. A roll 4 of papercarrying the radio program is coiled and positioned on the rolier 3. Aspindle 5 for the roller 3 engages in slots 6 in the parallel upwardlyextending arms 1 of the bracket 2. The slots 6 extend diagonally upwardwithin the arms and are so arranged that a pull on the strip of papercoiled around the roller 3 will tend to draw the spindle 5 into thelower end of the notches in the bracket.

A casing 8 is positioned over the device and has an opening 9 in theupper surface thereof through which the paper strip carrying the radioprograms is visible. If desired, in parallel relation to the opening 9,may be arranged a list I of broadcasting stations giving the position atwhich they may be found on the radio, although this is obviously not anessential feature of the present invention. The casing is suitablysecured to the base, the latter having a small flange I9 aiding inlocating the casing in proper position. The upper surface of the casingconsists of a pivoted cover II to provide for access to the casing; Thecover II is supported by hinges lia, and the opposite end engages ahorizontal flange 8a on the casing 8. The printed program may thus bereplaced by new weekly programs through the cover iI without removal ofthe casing from the base.

For advancing the paper from the roll 4 past the opening 9, a positivelydriven roller I2 supported by a bracket I3, corresponding substantiallyto the bracket 2 is provided. The upper end of the arms I3a forming thebracket I3 are each provided with a diagonal slot I4 to receive therounded ends of the square shaft I on which the roller II is mounted. Apinion I6 is carried by the shaft I5 between the inner side of theroller I2 and the inner arm I3a, and meshes with a gear I'I on acountershaft IB journalled in the inner arm I3a and also in the upwardlyextending support I9 secured to the bracket I3 or to the base. The shaftI8 also carries a. pinion 20 which meshes With a gear 2I, Fig. 2,secured to a shaft 22 forming part of a conventional clock 23, thelatter having the usual face for indicating the time. The clock issupported on a bracket 23a secured to the base, and the clock faceprojects through an opening in the casing to be visible at the sidethereof. The shaft 22 is so connected with the clock 23 as to providefor rotation of said shaft once every twenty-four hours. This is a usualand well-known clock construction and the gearing by which this rate ofrotation of the shaft 22 is procured need not be described.

As a radio is. in general, not extensively used between the hours ofmidnight and eight oclock in the morning the time table need not beadvanced during this period. In order thus to interrupt the paperadvance, (which incidentally reduces the length of paper required for acomplete weeks program) the gear 2| is mutilated and has the teeth overone-third of its periphery removed. These teeth are removed in theportion Which would normally engage with the gear 20 during the hoursfrom midnight until eight in the morning and accordingly during thispericd the time table is not advanced. The program as hereinafterpointed out, is printed to indicate at midnight the events for the nextfew hours.

For more positively holding the time table strip against the roller I2to assure advance of said strip at the predetermined rate to carry theprograms past the opening 9, the inner arm I3a of the bracket I3supports a horizontally extending arm 24 on which is journalled a roller25 having a bore therethrough materially larger in diameter than the arm24 to allow for a substantial amount of play between the pins 25a. Thearm 24 merely engages the upper end of the inner arm i3d and is carriedby the bracket 23a to which it is secured by an oiset part of said armin such a manner as to permit said arm to turn for raising said arm fromthe feed roller. The roller l2 is preferably provided with spaced belts28 of suitable frictional material, such as partially cured rubber,which assures a positive advance of the paper carrying the time table.As the strip is advanced, it passes through an opening 2l in the casingB and it may be torn oiI at intervals as desired, the roll beingperforated, if desired, for easier tearing.

In order that the program may be readable at night, the device may beilluminated from within, as by the provision of a suitable smallelectric light socket 28 intended to receive a bulb 29 positionedbeneath the opening 9. A suitable switch 39 is secured to the casing forcontrolling the illumination of the bulb 29 and the bulb may be in thesame circuit with the clock 23 if' the latter is electric. It is notessential, however, that the clock be electric, as it may readily be amechanical or spring actuated clock.

Referring now to Fig. '7, the paper strip 4 carrying the time schedulehas the program for each quarter hour, or other predetermined timeinterval during the day printed for each available station or for eachnetwork. As the strip of paper is fed a predetermined distance duringeach quarter hour, (the gearing being suitably proportioned) the programfor each such period must occupy a predetermined length of the paperstrip and accordingly where all of the space is not required forprograms, suitable advertising may be incorporated to avoid blank areason the strip. The strip stops its movement at midnight and at this pointthe program for the neXt several hours may be printed on the visibleportion of the strip. When the strip begins its movement again at anearly morning hour, (for example, eight oclock as above described), theprinted program succeeding the program visible at midnight is that forthe first half hour during the morning after that time at which thedevice starts to feed the strip of paper. The opening 9 is preferably ofa size to permit the program for twotime intervals to be visible at onetime.

Although the device has been described as starting and stopping themovement of the paper at predetermined hours, it will be apparent thatany more satisfactory hours may be chosen and the program may then beprinted accordingly. Moreover, in certain cases, the program may bearranged for longer or shorter periods than one week.

Instead of being a separate device, the invention may be incorporated asan integral part of a radio by being positioned within the cabinet. ASlOestshown in Fig. 6, the front of the radio cabinet. 3| has an opening9 corresponding to the Opening 9 provided in the casing for the deviceandthe mechanism above described is positioned within the radio cabineton a supplementari Support, not shown, secured to a panel 32 fOrmrlgpart qi the front wall of the cabinet. The panel 32 is suitably mountedon hinges 33 to permit said panel t the clock 23 is so arranged that theface ls v'"lmble at the front of the cabinet, said clock projectingthrough an opening in the panel 32. Since the angle of the clock to thefeed roll is different in the arrangement shown, it will be apparentthat suitable bevel gearing, or its equivalent, must be provided betweenthe clock 23, and the feed toll which advances the program past theopening 3".` Such an arrangement will be readily apparent and need notbe described. In this arrangement the illumination for the portion ofthe program visib-le through the opening 9, may be controlled by thesame switch 34 that controls the radio, or by a separate independentswitch 34 in the panel 32. The opening 9 is arranged to be closed by asuitable slide 35 normally hidden beneath the panel 32 and slidablelaterally to conceal the opening 9 when the time table described is notin use. Said slide is supported by suitable guideways, not shown, on theback of the panel 32 in the usual manner.

From the foregoing, it will be apparent that the device contemplates theadvance of a paper strip carrying a radio program at a predeterminedrate, past an opening through which said strip is visible, so that atany time during that period, the program for that period will bevisible. The program may be renewed at the end of each week and each newprogram is readily positioned in the device by the opening of the Coverand the substitution of the newly printed roll on the roller 3. Thisroller, as will be apparent, is readily removable by sliding the pin 5radially through the slots 6. The new roll having been positioned on theroller 3 and the latter having been returned to the position shown, thenewly printed strip of paper is then advanced in the desired manner bythreading the end of said strip between the roller 25 and the largediameter roller I2. It is necessary merely to properly locate theprogram with respect to the opening 9 when the strip is rst threaded.

I claim:

In a device of the class described, the combination with a printed stripgiving successively thereon, the radio program for only successive timeintervals for a portion of a day, and a clock, of means actuated by saidclock for advancing said strip only for the portions of the day forwhich the program is applicable, said means including a shaft driven bysaid clock and arranged to rotate once each day, and connections betweensaid shaft and the mechanism for feeding the strip for actuating themechanism for the same portion of each successive day, the mechanismbeing inoperative during the remainder of the day.
